I re-installed Windows 7, and one by one re-installed things with a restart between each successful install.
It turns out my video card driver is causing the issues.
I have an ATI Radeon 5450 graphics card installed in PCIe.
I used Driver Genious to get my driver and then I couldn't reboot (same black screen problem). System Restore got me going again.
I then went to ATI's site and tried their auto-detect tool to grab the driver, restarted and black screen. System Restore.
I went back to ATI two times, once to manually get the driver, and once for a beta, with the same black screen results.
What can I do?
I was going to try to flash my Video Card BIOS and see if that helped, but I couldn't find the correct BIOS file.
Any other ideas?
A little extra info:
I have had this video card for about 9 months and this is the first problem I've had. I bought it when my onboard graphics card managed to get cooked (the rest of my motherboard is fine).
I am still using the Radeon now, but dxdiag tool says "Standard VGA Graphics Adapter" instead of the proper name it used to have. I am not using VGA, I'm plugged in to HDMI.
My PC is:
OS: Windows 7 x64
CPU: AMD Phenom Quad Core 2300mHz
Graphics: ATI Radeon 5450
MB: Asus M4A78 Pro
